2020-05-30usb: dwc3: add make compatible for rockchip platformFrank Wang
RK3399 Type-C PHY is required that must hold whole USB3.0 OTG controller in resetting to hold pipe power state in P2 before initializing the PHY. This commit fixed it and added device compatible for rockchip platform.

2020-03-30usb: Migrate to support live DT for some driverKever Yang
Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT. This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use ofnode as parameter instead of fdt offset. And all the drivers who use these APIs update to use live dt APIs at the same time. Signed-off-by: Kever Yang <kever.yang@rock-chips.com>

2019-10-31dwc3-generic: Don't fail probe if clk/reset entries are absentVignesh Raghavendra
Some boards don't populate clk/reset entries as these are are optional as per binding documentation. Therefore, don't fail driver probe if clk/reset entries are absent in DT. This fixes fastboot failures seen due to enabling of CONFIG_CLK on AM57xx Fixes: e8e683d33b0c ("board: ti: am57xx-idk: Configure the CDCE913 clock synthesizer") Reported-by: Sam Protsenko <semen.protsenko@linaro.org> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com>
2019-10-24usb: dwc3: Add dwc3_of_parse() to get quirks information from DTJean-Jacques Hiblot
Add a new function that read quirk and configuration information from the DT. The goal is to allow platforms using their own version of DWC3 driver to migrate to the generic DWC3 driver. The function is adapted from the function dwc3_get_properties() in the linux dwc3 driver introduced in commit c5ac6116db35d. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-10-24usb: dwc3-generic: if no max speed is specified in DT, assume super speedJean-Jacques Hiblot
There is no need to fail if the maximum speed is not specified. If the speed is not specified, do the same as linux and assume super speed. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-10-24usb: dwc3-generic: add a new host driver that uses the dwc3 coreJean-Jacques Hiblot
Currently the host driver used by dwc3-generic is "xhci-dwc3". This is a functional driver but it doesn't use the dwc3 core and, in particular, it lacks some bits that may be important. For example on the k2 platforms, it is important that the phy are properly suspended when the USB is not used anymore. The dwc3 core also has a partial support for quirks. The new driver can be used as a drop-in replacement for "xhci-dwc3". In terms of implementation, it may seem strange that 2 private structures dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this is simply that the xhci layer expects a struct xhci_ctrl at the beginning of the private data and it seemed wasteful to include it also for the peripheral case.
